To all whdin it fittty concern.-

Be it known that I, ANTON OHNEMUS, a citi- Zen of the United States,residing at Quincy, in the county of Adams and State of Illinois, haveinvented certain new and useful Improvements in Nestable Stovepipes, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming partof this description.

My invention relates to that class of stovepipes so constructed thatthey maybe shipped in collapsed condition nested together, so as toeconomize space, the objectof the invention being to so constructpipe-sections of this description that they may be readily joined at themeeting edges by even. an unskilled workman and the seams being soformed that when produced they will be firmly held against lateral orlongitudinal displacement.

I am aware that it is not new to construct collapsible and nestableStovepipe-sections; but as heretofore made such sections have usuallybeen provided with the usual overlapping longitudinal tongues that formthe seams and the seams being secured by a rivet inserted in the upperend of such section to prevent the seams from springing open whenanother section of pipe is forced over the end thereof. Another methodof forming the seams has been to cut tongues from the pipe-sections thatoverlapped the tongues of the seam, so as to avoid its springing open.In the use of a rivet it is necessary that the person producing the seamto join the edges of the pipe-section be a workman who is capable ofapplying the rivet and has the necessary facilities for so doing. Theuse of the tongues referred to is objectionable in that they are liableto become broken or fractured in the process of manufacture of thepipe-sections or broken off in handling or transportation of thepipe-sec tions. It has been my aim to produceapipesection of suchconstruction that the objectionable features of such sections asheretofore made are entirely overcome and, furthermore, to produce anarticle in which the seam may be readily made by any person, whether askilled workman or not, the form of the article being such that it isonly necessary to use a hammer or mallet in making the seam and Isecuring it firmly to avoid liability of displace;

ment thereof. I H

Figure I is a perspective View of one end of a pipe-section constructedin accordance with my invention. Fig. II is an end view, shown enlarged,of the meeting or tongue edges of the pipe section. Fig. III is anelevation of the end of the section in open condition. Fig;

IV is an elevation showing the seam thereof secured. Fig. V is a Viewshowing a number of pipe-sections in collapsed condition nested togetherfor shipment.

l'designates a pipe-section provided with longitudinal tongues 2 and 3,designed to be interlocked with each other and to be flattened to form aseam by the use of a hammer or mallet in the usual manner in which suchseams are commonly made.

One of the edges of the pipe-section is cut away diagonally at 4 at theend of the section, the cut being produced through the outer tongue 2 aswell as through the adjacent portion of the body of the section. Whenthe seam is to be produced, the edges of the section are broughttogether so that the tongue 2 enters beneath thetongue 3, and thetongues are then flattened in the usual manner by the use of a hammer ormallet. The corner 3 at the end of the tongue 3 at this time projectsbeyond the diagonal cut-away portion 4 of the opposite edge of thesection to the extent, indicated by the dotted line A, Fig. III. Thecorner 3 of the'tongue 3 is then bent backward on the line A, Fig. III,over the diagonal cut-away portion of the opposite edge of the section,as seen in Fig. IV, and firmly hammered down, so as to secure the samein an effectual manner against springing open or against endwisedisplacement. It will be seen by which the tongues are flattened and the5 corner 3 is bent over and lapped onto the same. Moreover, there is nopart of the pipesection that is liable to become broken or injured inany way in the process of manufacture or in handling duringtransportation.

While I have referred to the herein deedges cut away at the end thereofto receive scribed pipe as a Stovepipe, I do notwish the coincidentcorner of the o'pposing tongue 10 to be restricted to a pipe of thisnature, as the when lapped thereover, substantially as deconstructionmight be of utility in other described.
